Abstract：A case of baboon syndrome is reported.A 58-year-old woman presented with a 4-day history of pruritic erythematous rashes on the left chest and abdomen,bilateral antecubital fos-sae,and axillae.The patient contacted a broken thermometer 5 days ago.She also had a history of contact allergy to a mercury-containing topical agent known as"red medicine".Dermatological examination revealed a large demarcated fresh patch on the left breast and abdomen.Symmetrically distributed dark red patches with clear boundaries were noticed in the bilateral antecubital fossae,axillae,and groins.The patches were blanched on pressure,and slightly warm could be felt.No erosions or exudation were observed.Laboratory examinations showed normal routine blood tests,liver and kidney function tests,blood glucose,and electrolyte levels.Hepatitis B surface antigen(HBsAg)was negative,while hepatitis B surface antibody(HBsAb)was positive.Electrocardio-gram(ECG)was normal.Diagnosis:Baboon syndrome.The patient was treated with oral ebastine tablets(10 mg once daily in the morning),oral cetirizine hydrochloride tablets(10 mg once daily in the evening),and topical calamine lotion(4-5 times daily)for 7 days.The skin lesions gradu-ally subsided on the 4th day of the treatment,accompanied by desquamation,and the lesions com-pletely resolved,with some residual hyperpigmentation by the 8th day.By the 10th day,the skin appeared normal.The patient is still under follow-up.
